The impedance changes as the electromagnetic field interacts with the material. The tested materials are limited to non-ferromagnetic materials such as austenitic stainless steel, admiralty brass, copper-nickel alloys and titanium. Initially, a coil is placed in a tube and balanced (impedance matching). The test probe is pulled, and variations in coil impedance are recorded and analyzed. The impedance changes are related to the size, shape and See more on process-heating eddy current testing method for 13cr44mo tubes MachiningSteel Pipe Hydraulic Test VS Eddy Current TestingFeb 22, 2019 · However, this method has a large area, high energy consumption and low efficiency. Most of the early eddy current testing uses the wave height comparison method, that is, only the magnitude of the detected eddy current signal is used to judge whether the steel tube has defects.
